Although Proteus mirabilis is a common human pathogen, bacteremia caused by the organism, especially strains producing extended-spectrum beta-lactamase (ESBL), has rarely been investigated. We examined 64 cases of P. mirabilis bacteremia identified in the Minami Ibaraki Area, Japan, between 2001 and 2010 and compared the characteristics of cases with(More)
To date, few cases of extraintestinal infection with Clostridium difficile have been reported. We describe a case of surgical-site infection with C. difficile following a colonic operation. Administration of metronidazole was considered to be effective for treatment of the infection. The isolate was a toxin A-nonproducing and toxin B-producing strain.
We used a real-time PCR assay to measure human cytomegalovirus (HCMV) DNA load in whole blood and plasma of 70 patients who were infected with human immunodeficiency virus type 1. Break points of 3.0 x 10(3) copies/mL in whole blood and 1.0 x 10(3) copies/mL in plasma were well-correlated with the existence of definite HCMV disease (sensitivity, 93% and(More)
Desulfovibrio species are anaerobic gram-negative, pleomorphic bacilli rarely causing infection in humans. In the present report, we describe a case of bacteremia caused by Desulfovibrio fairfieldensis. The patient, for whom biapenem was administered, rapidly improved without any sequelae. As far as we know, this is the first case report of infection by(More)
We executed a blanket-use program of intranasal application of mupirocin ointment to control the propagation of methicillin-resistant Staphylococcus aureus (MRSA) that occurred in a thoracic surgery ward of a university hospital. During an intervention of 14 weeks, all patients admitted to the ward for scheduled surgery received the ointment to their nares(More)
We report a case of thoracic empyema caused by Campylobacter rectus, an organism considered as a periodontal pathogen but rarely recovered from extraoral specimens. The patient fully recovered through drainage of purulent pleural fluid and administration of antibiotics. The present case illustrates that C. rectus can be a cause of not only periodontal(More)
Mycoplasma arginini, an organism usually recovered from mammals, was isolated from the blood of a febrile patient with advanced non-Hodgkin lymphoma. The patient's condition improved without administration of antimycoplasmal drugs. Simulation of blood culture showed that automated blood culture instruments may fail to detect the organism.
A 24-year-old male healthcare provider, having attended a varicella patient 2 weeks before, developed varicella himself. He had shown a positive result for anti-VZV antibodies measured with an immune adherence hemagglutination assay (1:4) 1 year before. The present case shows that a positive result with this assay does not necessarily indicate protection(More)
